Samsung has been quite active on the firmware update front, this year, or so it seems. They have now released another Android 4.1.2 Jelly Bean firmware update for Samsung Galaxy Note LTE 10.1 N8020. Samsung recently updated N8020XXBMA3 Android 4.1.2 Jelly Bean official firmware in Australia and few other countries.

The latest iteration of this firmware allows you to update your tablet from Android 4.1.1 Jelly Bean to Android 4.1.2 Jelly Bean. While the update is available via KIES and it is recommended that you get it from there. If for some reason, you cannot access the official update, here is a guide to update N8020XXBMA3 Android 4.1.2 Jelly Bean official firmware on Galaxy Note LTE 10.1 N8020 .

Disclaimer:This guide will use a tool; Odin to flash the official firmware on your Galaxy Note 10.1 LTE N8020. During the process, you might lose all your existing installed apps and personal settings. It is therefore necessary for you to follow the guide carefully. Also, please, do mind that this tutorial is only for Galaxy Note 10.1 LTE, model number N8020. Don’t try this guide in any other Android device.

Put the Galaxy Note 10.1 LTE 10.1 N8020 tablet in Download Mode by pressing and holding Volume Down and Power button until Samsung Galaxy logo appears in tablet screen. Wait for a few seconds and you will be in download mode.

Run Odin3 v3.07.exe (see Step 2) as an Administrator.

Connect your Galaxy Note 10.1 LTE 10.1 N8020 with your PC using USB cable. A message will appear under Odin’s message box in the bottom left saying “Added!!”. If you don’t get it, then try another USB port. If that too doesn’t work, then reinstall the USB driver. If you successfully see the “Added!!” message in Odin, you are good to go. Also, check for COM port with a number in Yellow to make sure that you have successfully added your device.

Select the following files in Odin at their respective tabs from extracted N8020XXBMA3 firmware folder :

Click the ‘PDA’ Button, and select the .tar file here with *code* appearing in file-name.

Click the ‘Phone’ Button, and select file with *modem* in its name (Ignore if no file exists).

Click the ‘CSC’ Button, and select file with *csc* in its name (Ignore if no file exists).

Click the ‘PIT’ Button, and select the .pit file. Use only if you got it while extracting in step 1 above, otherwise ignore it.

In Odin window, make sure Auto Reboot and F. Reset Time checkboxes are selected. Also, make sure that Re-Partition checkbox is selected, only if you are using a .pit file (see Step 7.4).

Recheck everything mentioned in Step 7 & Step 8 above. Hit the START button to begin the flashing process.
Once the flashing process is completed, the tablet will reboot automatically and you will see a PASS message in the top-left-most box. You can now unplug the USB cable to disconnect your device from computer.
